In this study, a novel technology for the comprehensive utilization of low-grade iron ore is presented. For the iron ore with a Fe content of 24.91%, a pilot-scale study of pre-concentration, suspension magnetization roasting, grinding, and low-intensity magnetic separation was conducted, and an iron concentrate with a grade of 62.21% and a recovery of 85.72% …

The results reveal that the simplest method, jigging, significantly enhances the iron content in the concentrate, achieving a total iron content of 50%. However, this outcome is heavily influenced by the size of hematite inclusions within the ore.
